Answers to the questions we get most. If yours isn’t here, email us and a real person will reply.
How do I play?
Tap anywhere to drop the floor the crane is carrying. Whatever hangs over the edge gets cut off. Line it up perfectly to start a streak: 3 perfects = x2, and perfect drops regrow the floor.
What is the Daily tower?
One seeded tower per day with the same crane timing and wind for everyone. It resets at midnight UTC. You can build it as many times as you like; your best score is posted.
My score didn’t show up on the leaderboard.
Scores post when you’re online. If you were offline, open the game again with a connection and it will retry. Check that you’ve set a name in Settings.
How do I unlock materials and builders?
Materials unlock as you reach new heights and streaks. Builders are cosmetic. Looks only: every builder plays the same.
The game feels laggy or the taps are late.
Close other apps, turn off Low Power Mode, and make sure the game is up to date. Turning on Reduce motion in Settings also lightens the effects.
Can I change or remove my leaderboard name?
Change it any time in Settings. To remove your name and scores entirely, email us from the device or include your current name and we’ll delete them.
Does Stack Up have ads or purchases?
No ads, no in-app purchases. The whole game is free.
